Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an ultraviolet dryer, which can perform ultraviolet disinfection such as sterilization, sterilization, and sterilization without damaging clothes, and has a long life of the ultraviolet lamp. Also related to the dryer that can be guaranteed.

(Prior Art) Recently, various dryers for clothes have been developed and commercialized, and when there is no drying space for laundry such as in an apartment or apartment in a city, or outdoors such as underwear for women. Even when it is not convenient to dry it in the room, it can be dried in a short time with a dryer in the room, which is very convenient.

In a conventional dryer, a rotary drum is provided in the housing of the dryer, the door on the front of the housing is opened, wet clothes after washing are put into the rotary drum from the entrance, and the door is closed while rotating the rotary drum. A method in which hot air is blown onto clothes or the like to dry them is common.

(Problems to be solved by the invention) However, when clothes and the like are dried outdoors in the sun, the ultraviolet rays contained in the sunlight hit the clothes and the like, so that the clothes and the like are sterilized and sanitized, and hygiene is maintained. However, the conventional dryer does not consider such sterilization at all, and there is a sanitary problem particularly when the dryer is used in so-called coin landry.

Of course, it is conceivable to increase the temperature of hot air to perform high-temperature sterilization, but there is a concern that such high-temperature sterilization may damage clothing, especially chemical fiber clothing.

On the other hand, as shown in Japanese Utility Model Laid-Open No. 55-11160 and Japanese Utility Model Laid-Open No. 63-3392, a dryer is provided with an ultraviolet lamp, and clothes put in the dryer are irradiated with ultraviolet rays to perform ultraviolet disinfection. A method has been proposed.

However, all of the dryers described in the above publications are provided with a protective glass in front of the ultraviolet lamp, but since wet clothes and the like are put into the dryer, the protective glass easily gets wet and stains adhere, If it is blocked, there is a concern that complete sterilization cannot be performed within the set time of the timer.

Further, Japanese Utility Model Laid-Open No. 63-3392 proposes to cover the front of the ultraviolet lamp with a stainless wire mesh instead of the protective glass. In such a case, ultraviolet rays are hardly blocked,
This time, there is a problem that the ultraviolet lamp is exposed to hot air and the durability is significantly reduced.

In view of the above problems, it is an object of the present invention to provide a dryer that can perform disinfection, sterilization, and sterilization without damaging clothes and can guarantee the life of an ultraviolet lamp. .

(Means for Solving the Problems) Therefore, the ultraviolet dryer according to the present invention, while drying the object to be dried contained therein by blowing hot air onto it,
In a dryer designed to irradiate the material to be dried with ultraviolet rays from an ultraviolet lamp to sterilize it, the ultraviolet lamp is provided between the irradiation position where the material to be dried should be irradiated with ultraviolet rays and the protection position outside the hot air blowing range. Is installed or provided with an ultraviolet lamp protection mechanism that blocks the blowing of hot air against the ultraviolet lamp at the irradiation position.When blowing hot air, the ultraviolet lamp protection mechanism moves the ultraviolet lamp to the protection position or While shutting off the blowing of hot air, after the blowing of hot air is completed, move the ultraviolet lamp to the irradiation position by the ultraviolet lamp protection mechanism or release the blocking of hot air blowing and expose the ultraviolet lamp inside the dryer. It is characterized in that the material to be dried can be irradiated with ultraviolet rays.

Here, the dryer is not limited to the rotary drum type, and may be of any type as long as it is a system of blowing hot air to dry.

The ultraviolet lamp may be provided at any position of the dryer as long as it can irradiate the object to be dried with ultraviolet rays, and may be provided, for example, at a door on the front surface of the dryer or inside the dryer.

Usually, an ultraviolet lamp does not have sufficient heat resistance, and if it is directly exposed to hot air, it causes a problem in durability. Therefore, it is important to provide a mechanism for protecting the ultraviolet lamp.

The ultraviolet light protection mechanism may be manually operated, or a separate drive source may be provided and automatically operated. Further, the ultraviolet lamp protection mechanism may be a mechanism that slides or rotates the ultraviolet lamp between the irradiation position and the protection position, or may be a mechanism that blocks hot air with a shielding member.

Further, the ultraviolet lamp may be provided with a switch and turned on and off to be operated, or a sensor for detecting the end of the hot air blowing is provided and operated by a microcomputer or the like based on the output of the sensor. You may

According to the present invention, an ultraviolet lamp is provided to irradiate the dried material with ultraviolet rays, so that the dried material is sterilized, sterilized, and sterilized. be able to.

Further, since the sterilization is performed by irradiating with ultraviolet rays and the sterilization is not performed by blowing hot hot air, the clothes are not damaged.

Moreover, since the ultraviolet lamp is exposed inside the dryer, the irradiation of ultraviolet rays is not blocked. Therefore, complete disinfection, sterilization, and sterilization of clothes and the like can be performed within a set time of a timer or the like.

By the way, if the UV lamp is always exposed inside the dryer, it is exposed to hot air and the UV lamp easily deteriorates.However, a UV lamp protection mechanism is provided, and the UV lamp is blown with hot air when the object to be dried is blown with hot air. Since it is moved to a protection position outside the range or the blowing of hot air against the ultraviolet lamp is blocked, even if the heat resistance of the ultraviolet lamp is not sufficient, the ultraviolet lamp is exposed to the hot air and the ultraviolet lamp deteriorates immediately. Can be prevented and the life of the UV lamp can be guaranteed.
